It's unclear how Apple might use the technology or whether it will make it into the rumoured iPhone 7.

No technology available on the market uses Li-Fi, so there is little to compare it to. One use could be talking to other devices within the same room, such as the Apple TV. The high data speeds mean a film could be sent from an iPhone to the TV within seconds, ready to stream. (This is just speculation, though — it's still early days for the technology.)
